GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 457,750, dated August 11, 1891.

Application led November 3; 1890. Serial No. 370,112. (No model.)

To a/ZZ whom it may concern:

Be it known that we, JOSEPH RIDDELL and RICHARD G. MORRISON, of Sharon, in the county of Mercer and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners; and we do hereby declare that the following is a full, clear, and

'whereby economy is secured in the cost oi' the burner, and also to provide for the perfect combustion of the gas, thus economizing in the matter of fuel also.

We have shown in the accompanying drawings the burners in connection with a range of steam-boilers; but it willbe understood that the burners are shown in this connection only for the sake of convenience, and maybe used in any other desirable situation.

In the drawings, Figure 1 represents a front elevation of a range of boilers with the burner under one represented in elevation, while the burner under the other is partly in section. Fig. 2 is a vertical section on the line .z .fr of Fig. 1. Fig. 3 is a horizontal section through the head of the burner on the line y y of Fig. 2.

rzI he gas is supplied to the burner from any suitable source through a stand-pipe g, and this stand-pipe carries upon its upper end the burner proper.

This'burner consists ot a hollow head of metal, which is formed, preferably, concavoconvex in cross-section, as shown to the right in Fig. l, being open at its rear end and with its front end, which projects into the furnace beneath the boilers, formed as a frustum of a cone. Supported-within the hollow head, which we have indicated at ct, is a gas-nozzle h, which, like the head, is concave-convex 1n cross-section, having its rear end closed, as shown in Fig. 2, while its front end 1s formed tapering, corresponding to the shape of this end of the head. Between this nozzle and the inner wall of the hollow head is provided an air-space i, which is open to the outside air, as shown in the right of Fig. l. The nozzle covers the opening leading from the standpipe, as shown in Fig. 3, and directs the gas to the tapering exit of the nozzle, as at CZ.

Instead ot' the hollow head being of metal and formed as a part of the burner proper, it may be located in the brick-work of the furnace-wall and constructed of any suitable material, and if made of metal it may be either of one piece or in sections, as desired.

Across the frontof the hollow head we support a bar or plate c, which serves as a bearing for a turning screw f, provided with a hand-wheel. The end of this screw engages with an opening in the rear wall of the gasnozzle, whereby the said nozzle may be adjusted so as to increase or diminish the space between it and the contracted end of the hollow head, thus regulating the supply of air needed for the perfect combustion of the gas issuing from the nozzle. The gas-supply pipe g has horizontal lianges g at its upper end, and upon these rest the flanges of the nozzle, and from this construction it will be clear that when the nozzle is adjusted the joint at the flanges will always be covered, and there will be no opening Vformed through which the gas may leak without passing through the nozzle. By the use of this device we obtain complete control of the quantity of air introduced, as well as the manner of introducing it in a thin body, thus insuring a perfect combustion, and requiring but a comparatively small amount of gas to accomplish the desired result.

We do not of course limit ourselves to the precise arrangement of the hollow head, gas1 nozzle, and supply-pipe, as the supplymaybe connected with the nozzle from above, if desired, or from one side, very slight changes in construction being required for this purpose.

Having described our invention, what We with the other end contracted and an opening hood or nozzle is permitted without allowing leakage, and an outer hood or nozzle inclosing the inner, each hood or nozzle being formed with a contracted portion at one end, with an opening therein, substantially as described.

In testimony whereof we aiiix our signatures in presence of two witnesses.
